Adverse childhood experiences and developmental outcomes in adolescents in residential care: A comparison of cumulative and person-based approaches
This study demonstrates that combining cumulative and person-centered approaches provides a more nuanced understanding of how adverse childhood experiences impact developmental outcomes in adolescents in residential care, revealing that specific patterns of adversity, such as high ACEs with low neglect, are particularly detrimental.

For many young people, the path to adulthood is paved with challenges that can be overcome with time and support. But for a specific group of adolescents living in residential care facilities, the journey often begins with a heavy burden of early trauma. These young people have faced what researchers call adverse childhood experiences, a term that covers a wide range of painful events, from living with family members who struggle with addiction or mental illness, to witnessing violence in the home, or suffering direct abuse and neglect. Scientists have long known that these experiences are harmful, but they have debated how best to measure that harm. One way is to simply count the number of bad events a child has faced, assuming that more events equal a worse outcome. Another way is to look at the specific mix of events, recognizing that different combinations of trauma might affect a child in unique ways. Understanding which method tells the truest story is crucial, because it determines how caregivers and doctors design help for these vulnerable teenagers.
A team of researchers in Spain set out to test these two approaches by following a group of 161 adolescents living in residential care facilities in the Galicia region. These young people, ranging in age from 12 to 18, had been placed in care because they could not safely remain with their families due to reasons such as abandonment, severe behavioral issues, or parental incapacity. The researchers gathered information from two sources: the group care workers who knew the children's histories, and the adolescents themselves, who reported on their own feelings and behaviors. The workers provided details on seven specific types of adversity, including family substance use, mental health problems, criminality, exposure to domestic violence, and various forms of abuse and neglect. The teenagers then described their own struggles with anxiety, depression, anger, and trauma-related symptoms. The study tracked these young people over two time points, with a follow-up eight months later, to see how their early experiences shaped their development over time.
When the researchers first looked at the data using the simple counting method, they found a general trend that matched expectations: the more adverse experiences a teenager had faced, the higher their scores were on negative outcomes like trauma symptoms and behavioral problems. However, the picture was not perfectly clear. While those with the highest number of bad experiences generally struggled the most, the difference between those with a few bad experiences and those with many was not always sharp. The counting method treated every bad experience as equal, but the data suggested that the specific nature of the trauma mattered just as much as the total number.
To get a clearer picture, the researchers used a more detailed method that looked for natural groups within the data. Instead of just counting, they asked if the teenagers fell into distinct patterns based on the types of trauma they faced. This analysis revealed three clear groups. The first group, which made up the majority of the sample, had experienced relatively few adversities. The second group was characterized by a moderate number of bad experiences, but with a very specific and severe focus on neglect; these teenagers had been let down by the adults who were supposed to care for them, suffering from a lack of physical and emotional support. The third group had experienced a high number of adversities, including violence and abuse, but surprisingly, they did not show the same high levels of neglect as the second group.
The results showed that the way you look at the data changes what you see. The group with the highest number of bad experiences did not always have the worst outcomes when compared directly to the group defined by severe neglect. In fact, the two groups with the most difficult histories—the one defined by high neglect and the one defined by high violence—both showed significantly worse mental health and trauma symptoms than the group with fewer adversities. Crucially, the study found that simply adding up the number of bad events missed the nuance of the situation. For instance, a teenager who had experienced three different types of adversity might be grouped with someone who had experienced four, but if the three included severe neglect, their needs and risks might be very different from the person with four less severe events.
The researchers concluded that while counting the number of bad events is a useful starting point, it is not the whole story. The specific combination and severity of the trauma, particularly the presence of neglect, play a vital role in shaping how a young person develops. By looking at the distinct profiles of these teenagers, the study suggests that understanding the specific mix of challenges a child faces provides a more accurate map of their needs than a simple tally ever could. This approach helps explain why some young people with many adversities manage to function better than others, and it highlights that the type of pain a child endures is just as important as the quantity. For the adults working with these teenagers, the findings offer a clearer path forward: effective support must be tailored not just to how many bad things happened, but to exactly what those things were.
